ASA 5510 Questions

[d8k2s9g2k]

ASDM Version: 7.1(2)

ASA Version: 5.1(2)

I have three questions that I have not been able to get solid answers for and I was hoping the experienced here could offer help:

1. What is the safest way to upgrade an ASA 5510 to 7.2. For example, save running config to file, upgrade/boot new image, copy config back? Please provide proven procedure because I have not seen any exact procedure in any of the CISCO books that I have. What are the gotchas?

2. When Monitoring the Properties tab (after Clicking Monitoring->Properties in ASDM GUI) over a VPN, at the bottom of the screen it says "contacting device for latest monitoring data". However, the progress bar never gets above 72% and then errors out with a warning about not getting a response from ASDM in 60 seconds. Why is this?

3. None of the books I have discuss the configuration for the dns keyword in the config file, for example, in my config I have:

dns dmain-lookup inside

dns server-group DefaultDNS

name-server xxx.xxx.xxx.xxx

name-server yyy.yyy.yyy.yyy

What is the ASA device actually using this information for? Clients are not querying the router for DNS information, so how is this used?

Any help with any of these questions would be appreciated,

Thanks,

-Rick

Check the requirements for running the software version from the Release Notes.

Download the ASA Software Image.

Copy the downloaded file to a tftp server.

Issue the hostname(config)# copy tftp flash command on the ASA to copy the ASA image and PDM image, one at a time.

Add these lines in the ASA configuration:

hostname(config)# boot system disk0:/asa711-k8.bin

hostname(config)# asdm image disk0:/asdm511.bin

Note: Before adding the lines specified, ensure that any other boot system and asdm image commands are removed.

Reload the PIX Appliance in order to boot with the new image.
